  FIG. 1 shows an example of a public wireless LAN system according to the present invention, which serves as an access point. A wireless LAN device 10 (router device) is accessed from a plurality of portable wireless terminals 1, a router 2 that establishes a wireless LAN between them, a router management device 3 that monitors and manages the router 2, A storage 4 (for example, a USB memory) as a large-capacity memory connected to the router 2 is provided. A plurality of such public wireless LAN devices 10 are connected to the Internet 5 to form a plurality of access points and are collectively managed by a server 6 as a remote terminal connected to the Internet.

  FIG. 2 shows that such a public wireless LAN device (router device) 10 is installed in the upper part of the vending machine 8, and a plurality of such wireless LAN devices 10 (access points) are connected to the Internet 5. An example in which the server 6 is collectively managed is shown. Reference numeral 9 denotes a wireless LAN antenna. In this way, the upper part of the vending machine 8 is a normally vacant space, and by using this, the public wireless LAN device 10 (access point) is installed, so that no special support structure is required, and vending Since the users who have the wireless portable terminals 1 around the machine 8 can easily gather, the sales of the vending machine 8 can be improved.

  FIG. 3 is a block diagram of the router 2, the router management device 3, the storage 4, and the server 6 as described above. The router 2 is connected to the CPU 11, the ROM 12, the RAM 13, and the I / O port 15 (input / output interface) via the bus 14. A transmission / reception LAN antenna 9 is connected to the I / O port 15, and for example, the Wi-Fi terminal 1 is connected to the antenna 9 so as to construct a wireless LAN. In order to connect the router 2 to the Internet 5, for example, an external radio wave antenna 16 connected to the I / O port 15 is provided, and this and the radio base station 17 are connected by radio communication, so that the router 2 Connected to the Internet 5. Of course, as shown in FIG. 4, instead of connecting the router 2 to the fixed Internet network 5 via the external radio wave antenna 16 and the radio base station 17, the router 2 is connected to a modem / converter 18, optical / DSL / cable, etc. It is also possible to connect to the public Internet network 5 via the fixed net line 19.

  Returning to FIG. 3, the ROM 12 of the router 2 generally stores a connection program for connecting to the Internet 5 and a communication program for communicating with the Internet 5 in the connected state in the same manner as known ones. As a program unique to the present invention, a user access program executed when the router 2 receives access from the user's wireless portable terminal 1, a server transmission program for transmitting necessary data to the server 6, and a command from the server 6 Stores a command receiving program and the like to be executed upon receipt. The router 2 is provided with, for example, a USB hub 20 as a connection terminal of the storage 4, and the storage 4 such as a USB memory is inserted into the USB hub 20 and connected to the router 2. The power of the router 2 is taken from the connection outlet 22 of the router management device 3, and the power supply circuit 23 is connected to the I / O port 15.

  In the storage 4, router browsing screen data that the user of the terminal 1 browses when the terminal 1 is accessed by the router 2, download data that can be downloaded to the user's terminal 1 on the screen, and the user terminal 1 is the router 2 Stores access history (log data, etc.), other AP configuration, firmware data, etc., and router operating time zone data that operates router 2 only for a limited time zone excluding midnight and early morning. ing. As will be described later, the data stored in the storage 4 can be collected and changed by command / distribution from the server 6, and the data stored in the storage 4 can be sent to the server 6. It is also possible to store all new data from the server 6 in the storage 4 in the initial setting state.

  The configuration is a file for mainly describing environment settings in DOS (disk operating system). The configuration is described as a text file, and is stored in the root directory of the activated drive (router, etc.). Saved. Setting information such as memory settings and connection status of peripheral devices is defined in the config. The config is read first when the system is started, and then the configuration file is read sequentially. The config is a simple text file that can be easily edited. When the computer is restarted, the changes made in the config can be reflected. Therefore, it may be beneficial to rewrite the configuration by transmitting it from the server 6 to each AP.

  In the router management device 3, a CPU 25, a ROM 26, a RAM 27, and an I / O port 28 (input / output interface) are connected to each other via a bus 24. The ROM 26 has a freeze monitoring program for monitoring the freeze of the router 2, a router temperature monitoring program for eliminating the router 2 when the temperature becomes higher than a predetermined temperature, and a router operation time management program for managing the operation time of the router 2 Etc. are stored. The program stored in the ROM 26 is specialized mainly for monitoring and management of the router 2.

  The router management device 3 obtains power by inserting the power plug 30 into the AC power source 29, and the power circuit 31 is connected to the I / O port 28. The power circuit 31 includes a router power on / off circuit (device). 32 is connected, and the above-described connection outlet 22 is connected thereto. The router power on / off circuit 32 is connected to the I / O port 28 and turns on / off the power to the router 2 according to a command from the CPU 25. That is, the router 2 receives power from the router management device 3, and the power supply path from the AC power source 29 to the plug 30, the power circuit 31, the router power on / off circuit 32, the connection outlet 22, the plug 21, and the power circuit 23 is determined by the router power on / off. When the circuit 32 is turned off, the power supply to the router 2 is cut off. Thereafter, if the router power on / off circuit 32 is turned on, the router 2 is restarted. Such a process is effective as a resolution process when the router 2 is frozen.

  The server 6 is connected to the Internet 5 through, for example, a fixed (wired) network line 32 a and a modem 33. Alternatively, the server 6 can be connected to the Internet 5 via an external radio wave antenna 16 and a fixed base station 17 as shown in FIG. The server 6 is connected to the CPU 34, the ROM 35, the RAM 36, and the I / O port 37 (input / output interface) via the bus 32b. Further, for example, a hard disk 38 (HDD) or the like is connected to the I / O port 37 as a large-capacity memory, and this HDD 38 mainly functions as a database memory. For example, the HDD 38 has router browsing screen data to be browsed when a user accesses the router 2 to use the public wireless LAN service, download data guided on the screen, AP configuration firmware data, and router 2 operating time. Router operating time zone data for setting the zone, access point data for identifying a plurality of existing access points managed collectively by the server 6, access logs collected when the user accesses the router 2, and user terminal data (this Is transmitted from the storage 4 connected to the router 2 via the Internet 5), and further, the mail address / MAC address registration data requested for registration when the user accesses the router 2 (also from the router 2 side to the server 6 To serve To) and the like are stored.

  The router browsing screen data, download data, AP configuration data / firmware data, router operating time zone data, etc. are the original data stored in the storage 4, and are empty storage via the Internet 5 from the server 6. New data can be communicated to and stored in the server 4, or the correction / change data can be sent from the server 6 to the storage 4 to be rewritten (updated).

  FIG. 4 shows a flow of data transmission / reception relation between the server 6 and the router 2 side. For example, the data flow from the server 6 to the AP (access point) connection storage 4 is corrected / changed by the server 6. The router browsing screen (redirect browsing screen) data (WEB data) of the previous day can be rewritten. A route from the wireless LAN router 2 to, for example, the Wi-Fi terminal 1 by a dotted line indicates that the redirect browsing data can be easily corrected / changed by the server 6. Note that a plurality of the wireless LAN router 2 and each terminal 1 construct the wireless LANs (1) to (3) at the same time, and there is no actual device in that portion. The life and death monitoring device 3 is mainly a freeze monitoring with a name focusing on a certain scene of the router management device 3. For example, the storage 4 inserted into the USB hub 20 functions as a mass storage area.

  In the flow from the server 6 to the AP (access point) connection storage 4 in the second stage of the server 6, the download data (file) for the access user is also updated by modifying the data from the server 6 to the storage 4. Can be rewritten to the state. This flow is indicated by solid arrows.

  The third stage of the server 6 is the flow of data from the AP-connected storage 4 to the server 6 in the reverse flow. Access history / log data (including terminal information) for each AP is transmitted via the Internet 5. Can be sent to the server 6 to collect the data. This is shown as a dashed line flow.

  As the flow from the AP (access point) to the server 6 in the fourth stage of the server 6, the information on the terminals used at each AP such as the registered mail address / MAC address information input when accessing the router 2 is also provided on the Internet 5. Can be collected to the server 6 via. This flow is indicated by a two-dot chain arrow.

  Further, remote maintenance can be performed by sending AP configuration / firmware data and the like from the server 6 to each access point (AP). And the administrator according to the hierarchy of the server 6 can do the report main of an access log or data terminal information. For this purpose, the printer 40 connected to the I / O port 37 of the server 6 in FIG. 3 via the driver 39 can print the access log / user terminal data stored in, for example, the HDD 38 and output a report.

  FIG. 5 shows an example of a screen that first appears on the terminal 1 of the user when the user accesses the router 2. This is an access user browsing screen (redirect browsing screen) 41. This screen 41 includes, for example, advertisement information, useful life information 42 corresponding to the access point, such as weather forecasts, suitable information on city halls, evacuation sites at the time of disaster, events in the district (festivals, events, etc.), A download file 43 (provided with icons and file names from A to F in this example) for displaying a download service for the accessed user is displayed. When the user clicks on the downloaded location and clicks the download execution button 44, the selected file is downloaded to the user's terminal 1 through the wireless LAN. When the Internet connection button 45 written as “connected to the Internet 5” is clicked, the user terminal 1 is further connected to the Internet via the router 2, and various information can be collected through the Internet 5.

  Next, the contents of the various programs described above will be described based on the flowcharts of FIGS. The program in FIG. 6 is a user access connection flow and corresponds to the ROM 12 connection program, communication program, and user access program in the router 2 in FIG. As shown in FIGS. 1, 2, and 3, when a user terminal 1 accesses the router 2 (S1), firewall processing is performed based on the log data (including terminal information) (S2). If that access is eliminated, it ends without access. If it is not excluded, it is determined in S4 whether it is necessary to input a mail address. This is the wireless LAN connection of S11 if the e-mail address or the like is not required as a system in this connection program. However, if the e-mail address is required in order to ensure a certain level of security, the e-mail is sent in S5. Whether or not the address has been registered is asked. If it has not been registered, the user inputs an e-mail address in S7. The processing of S8 and S9 is processing on the server 6 side via the Internet 5, the mail address input in S7 is sent to the server 6 in S8, the mail address registration and the MAC address registration are performed in the server 6, 3 is stored in the HDD 38 of the third server 6. In step S9, a password is transmitted from the server 6 to the router 2, and in step S10, the user acquires the password in the terminal 1 of the user. Once the password is acquired, it is registered in S5, and when the password is input in S6, the wireless LAN connection in S11 is established.

  In order to guarantee free access in the public wireless LAN service, no special input such as a mail address is required, and the log data (including terminal information) at the time of access is stored in the storage 4 in S12. In S13, the unique browsing screen data as the router 2 is read from the storage 4 and transmitted to the access source terminal 1. An example of the browsing screen is shown in FIG. If the user wishes to download by viewing the screen, a download command is issued by S14 when the download execution button 44 or the like is clicked. In S15, the CPU 11 of the router 2 reads the download data selected by the user from the storage 4 and accesses the access source. Download to the terminal 1.

  Thereafter, when the Internet connection button 45 is clicked on the screen displayed in S13, if there is a connection instruction to the Internet in S16, the connection is made to the Internet in S17 at this stage. After that, communication processing by Internet connection is performed in S18 as in the conventional case, and if there is an Internet disconnection command in S19, the Internet is disconnected in S19 'and the processing ends.

  The browsing screen of S13 is always transmitted to the user terminal 1 before connection to the Internet 5, and the router 2 can provide effective data by the user instead of being simply a connection entrance to the Internet 5. In addition, unlike downloading from a website on the Internet, the download data stored in the storage 4 is read and downloaded to the user terminal 1, so that data can be supplied at high speed and in a short time.

  FIG. 7 shows a transmission process from the server 6 to the router 2. This processing corresponds to a data storage / data correction / change program for an AP (access point) stored in the ROM 35 of FIG. 3, a remote maintenance program, and the like. In FIG. 7, when S20 determines that data is transmitted to all access points from the server 6 to the router 2, in S22, all access points serving as supply destinations are read from the HDD 38 of the server 6 to the access points. If not transmitted to all, an access point is designated in S21.

  In S23, it is determined whether or not new data is to be transmitted. In S24, it is determined whether or not the data is modified / changed. When the data is neither new data nor modified, data synchronization processing between the server 6 and the router-connected storage 4 is executed ( S25).

  Further, if the data to be transmitted is browsing screen data at the time of user access (S26), new data or correction / change data of the browsing screen is transmitted from the server 6 to the router 2 in S27, and to the router connection storage 4 in S28. Written. For example, similar data can be collectively stored from the server 6 in the storage 4 of all access points.

  In the case of transmission of download data in S30, new data for download or correction / change data is read from the HDD 38 of the server 6 in S31, and is written to the router connection storage 4 in S32 via the Internet 5. As a result, the data that can be downloaded by the user can be freely changed to the latest without going to each access point.

  If the AP configuration firmware data is determined in S33, the data is read from the HDD 38 of the server 6 in S34 and written to the router connection storage 4 via the Internet 5 in S35. This makes it possible to easily change data such as the most appropriate firmware.

  If it is determined in S36 that the router operating time zone data is to be transmitted, the router operating time zone data is read from the HDD 38 of the server 6 in S37, and is sent to the router 2 via the Internet 5 in S37 to the storage 4. It can also be stored or written to the RAM 27 of the router management device 3 via the LAN cable 25. If the data sent from the server 6 to the router 2 is not the browsing screen data of S26, neither the download data of S30 nor the data of the AP configuration etc. of S33, nor the router operating time zone data of S36, other new data is sent in S39. Alternatively, the process of transmitting the correction / change data to the router 2 is executed, and the data is written to the router connection storage 4 or the RAM 13 of the router 2 in S40.

  When synchronizing the data between the server 6 and the storage 4 in S25, the synchronization data is transmitted from the server 6 to the router 2, and the router connection storage 4 is overwritten. This is close to the correction / change of new data, but if it is unclear whether the data in the storage 4 and the data in the server 6 match, the data mismatch is resolved if this synchronous data is sent uniformly.

  FIG. 8 is a flowchart showing a transmission process from the router 2 to the server 6. This is a flow corresponding to the server transmission program of ROM 12 in the router 2 of FIG. The trigger for data transmission to the server 6 is exemplified by the three types of immediate transmission of an emergency matter in S52 when there is a transmission request from the server 6 in S50, or when a predetermined transmission time to the server 6 in S51 comes. can do. Even if there is no transmission request from the server 6, if the transmission time to the server 6 arrives, the flow of transmission to the server 6 starts, and even if there is no transmission time to the server 6, there is a transmission request from the server 6. If it is, the same processing is performed. Even if the requirements of S50 and S51 are not satisfied, in the case of an urgent matter, the determination of immediate transmission is made in S52.

  In the flow from S50 and S51, if the access history / log data is transmitted in S53, the CPU 11 reads the access history / log data (including terminal information) from the storage 4 in S54, and the read data is read in S55. It transmits to the server 6 via the Internet 5. Although the data transmitted to the server 6 may remain in the storage 4, the read area of the storage 4 can be cleared as in S56. The transmission history can be recorded in the storage 4 in S57. On the server 6 side, the data transmitted from the router 2 is written into the HDD 38.

  If the router 2 freeze data is transmitted in S58, the router 2 freeze history / freeze recovery (router power off) data is read from the storage 4 in S59, and the data read in S60 is sent to the server 6 via the Internet 5. To send. The server 6 stores the data in the HDD 38.

  When the overheat data of the router 2 is transmitted in S61, data such as the router overheat history and the router suspension period is read from the storage 4 in S62, and the read data is transmitted to the server 6 via the Internet 5 in S63. Sent. The storage process in the server 6 is performed in the same manner as before.

  When transmitting other required transmission data to the server 6 in S64, the data is read from the storage 4, for example, and the data read in S65 is transmitted to the server 6.

  When immediate transmission of an emergency matter is performed in S52, data such as router power-off (forced stop) due to difficulty in freeze recovery of the router 2 or difficulty in overheating of the router 2 is transmitted to the server 6 in S66, for example. In this case, when such an emergency that cannot be restored by the router 2 occurs, the information is immediately transmitted to the server 6, and although not shown in detail, the server 6 displays an emergency warning. For example, the fact that the access point that has become inoperable among a plurality of access points is displayed in red or flashing or a warning is given to the administrator to quickly notify the fact.

  FIG. 9 is a flowchart of router management (monitoring). This is a flow corresponding to the freeze monitoring program, router temperature monitoring program, router operating time management program, etc. stored in the ROM 26 of the router monitoring device 3 in FIG. For example, if the management (monitoring) order is set in S70, for example, the life and death monitoring (freeze monitoring) in S71, the router temperature monitoring in S80, the operating time zone management of the router in S86, etc. It is predetermined whether to monitor or manage in time.

  In the case of alive monitoring in S71, the router management device 3 outputs a monitoring signal (confirmation signal) to the router 2 in S73 at a monitoring timing (predetermined sampling time) in S72. When the CPU 11 of the router 2 in FIG. 3 receives the monitoring signal, the CPU 11 can output a response signal. However, if the CPU 11 cannot operate (freeze), it is determined in S74 that there is no response signal, and the router management device 3 The CPU 25 turns off the router power supply on / off circuit 32 and cuts off power to the router 2.

  In S76, the router power on / off circuit 32 is turned on for restart. If it is determined in S77 that there is a response signal, this means that the abnormality of the router 2 such as freeze has been resolved, and the process ends. If there is no response signal in S77 (In this example, if freeze etc. is not solved by one restart, it moves to S78, but if it is not good once, it restarts twice and three times. If there is no response signal, the process may proceed to S78.) In S78, the router 2 determines that the abnormality such as the freeze of the router 2 cannot be recovered, and the router power on / off circuit 32 is turned off so that the router failure Send the message to the server 6.

  In the case of monitoring the router temperature in S80, the temperature sensor signal of the router 2 is read in S82 at the monitoring timing of S81. If the temperature of the router 2 is equal to or lower than the allowable limit in S83, the process ends as no problem, but if it exceeds the allowable limit, the CPU 25 turns off the router power on / off circuit 32 and pauses the router 2 in S84.

  If the temperature of the router 2 falls below the allowable limit due to the suspension in S85, it is determined that the problem of overheating has been solved, and the process ends. Even if the router 2 is suspended in S84, if the overheated state of the router 2 does not fall below the allowable limit in S85, S79 is executed to send a message of failure due to overheating of the router 2 to the server 6. When managing the operation time zone of the router 2 in S86, it is determined whether or not the operation start time of the router 2 has arrived in S87, and if it is determined that it has arrived (timer on), the router power on / off circuit 32 is determined in S88. Turn on the router 2 and turn it on. In S89, it is determined whether or not the end of the operation time of the router 2 has arrived. If it is determined that it has arrived (timer off), the router power on / off circuit 32 is turned off and the router power is turned off. In other words, the operation of the router 2 starts when the operation time set by the timer arrives, and the operation of the router 2 ends when the end time set by the timer arrives. Thereby, the operation of the router 2 in the time zone such as midnight and early morning can be stopped.

  If the management of the router 2 does not correspond to any of the above, the other management of S91 is executed and the process ends. As described above, the operating time zone of the router 2 can be freely set for each access point by a command from the server 6.

  The typical processing flow has been described above with reference to the flowcharts. The signal flow focuses on each of the major elements in FIG. 10, that is, the terminal 1, the router 2, the monitoring device 3, the storage 4, the Internet 5, and the server 6. Is shown conceptually as shown in FIGS.

  In FIG. 11, an access request is sent from the user terminal 1 to the router 2, the initial screen data is read from the storage 4 and viewed on the terminal 1, and the download data is read from the storage 4 and stored in the terminal 1 in response to the download request. The Further, when an internet connection request is made by the router 2, it indicates that the terminal 1 can communicate with the internet connection.

  FIG. 12 shows a flow in which data is transmitted from the server 6 to the router 2, and a browsing screen and download data when the router 2 accesses the storage 4 are written into the storage 4.

  FIG. 13 shows an exchange in which a connection history data (log data, etc.) read command is sent from the router 2 to the storage 4 based on a command from the server 6, and the connection history data read from the storage 4 is sent to the server 6. ing.

  FIG. 14 shows that a confirmation signal is sent from the monitoring device 3 of the router 2 to the router 2, and a response signal (reply) is sent from the router 2 to the server 6 from the management device 3 via the router 2. .

  FIG. 15 shows a flow in which the above-mentioned maintenance data is transmitted from the server 6 to the router 2.

  Although the embodiment of the present invention has been described above, the present invention is not limited to the specific description, and the illustrated configuration, processing, and the like can be appropriately combined within the scope of technical contradiction. In addition, certain elements and processes can be replaced with known forms.
